question about an umbilical cord coming out?

Its me again pregnant with twins now 18 weeks. Last week I was here because the water broke around one of the twins. I have been under strict medical care since then. Well Wednesday night the cord of that baby came out. I am just going through it. I was rushed to the hospital. They told me that now my chances of infection are more likely. But that my cervix was still closed and I show no signs of labor. So they sent me home this time on antibiotics, because other than me giving them perm mission to deliver the babies now there is nothing they can do. Chance of survival right now is 0 so I do not want to do that. They told me if I could make it to 24 weeks I would have a chance of them surviving.

I am just going through it and do not know what to do.

Any words of of advise?
